` AUTOMATIC sAFiiGUARD.

Application filed Junea, `1923, serial No. seaiezfnn'ewea December as,1925.

To all fui/10m t may concernev i Y Be it known that I, JosiirrrGoULii'r, a citizen of Dominion of Canada, and resident of Timmins, inthe district of Cochrane and Province of Ontario, Dominion of Canada,have invented certain `newi'and,useful Improvements in Automatic'Safeguards, of

which the following is a specification. l

This invention relates to safety devices and particularly to 'a devicewhich would be usedl in connection with a mine cage.

The primary object of my invention is to provide an automatic operatedmember which will be in operative position when the cage vis even withv'one of the levels inthe mine and which will be inoperative positionwhen the cage is either above or below the level referred to. f

"lVith the foregoing and other objects in view as will appear as thedescription proof co-operatingelements as hereinafter more specificallyset forth, claimed and'shown in the accompanying drawings forming a partof the present application, in which:

Fig. 1 is a side elevation of a mineshaft looking 'at theV same from theiside,` ldotted lines indicating the position ofthe mechanism when'thecage is in the-position as indicated 'by dotted lines.l

1 Fig-'.2 is'a sectional 22ofFig-1gf4 Fig. '3 is an enlarged detaillview of one of the stop members.

Fig. 4 is an enlarged detail view` o f the method of hinging theliftplates. 1

5 indicates the corner timbers commonly used in framing amine shaft. 6indicates the guide timbers, 7 indicates the cage having sideguide-channels 8.

The cage 7 is provided at its opposite sides with curved channel members9 having flared upper and lower ends as more particularly illustrated inFig. 1. These curved channel members are suitably bolted or riveted ontothe side brace members ofthe cage as at 10.

At each level I provideoppositely positioned side braces or plates 11which are suitably engaged between one of the corner timbers and one ofthe guide timbers. These side plates 11 are provided with thelongitudinal slots 12.

13 and 13 indicate fulcrum plates suitview taken on liiie ably attachedto the.: corner timbers 5 and extending inwardlythereof. 14 and 14 arelevers fulcrumed on theplates 13 and 13, the levers 14 and 14 beingconnected respectively at their lower and upper ends to the link 15. Thelever 14 also has its upper end connected to the link 15. The inner orfree end of the link l15 is provided with a guidewheel 17 extendinginwardly therefrom and a guideblock 18 extending outwardly therefrom.:The guide wheel 17 will be operated by the curved channel member 9 asthe said channelmember passes up and down in connection with the cage 7.The relative positionof the channelmember 9 and the guide wheel 1-7 -isclearlyy illustrated in Fig. 2. The guide block 18 reciprocates inthelongitudinal slot 12 in the side pla-te 11. If the lever' has tracksentering from the opposite sidesofthe cage, the mechanism including thelevers14 and 14" at the opposite sides'of thecage will/be operated atthe opposite sides or entrances to the shaft.

19illustrates I a lplatform preferably made from channeliiron. VRivetedat `the inner cornerso-f this channel iron are hinge pin receivingmembers 20. "The corner timbers 5 are provided with plates 21counter-sunk into the corner timbers, las clearly illustrated in Fig.3.' The plates 21 are provided with hingepins 22supported therein by anysuitablefkinetliod.-` The plates-11 are provided with -an inwardlyextended flange 23, the purposeof which will hereinafterlbeidescribed..y Theplatform 19 is provided with suitable eye bolts 24which eye bolts Vare hingedly connected with ythe links 16. The cornertimbers are vertical when in their proper position and the flanges 23are set at an angle so that when the platform 19 is hinged upwardly thetop of the same will be tilted inwardly and thus remain in that desiredposition until forced back to operative position by the link 1G.

Having described the working mechanism I will "now describe theoperation. The curved channel members 9 travelling up and down with thecage 7 will at each level engage with the guide, wheels 17. When thecage travels either up or down from any vertical level it will leave theguide wheels at the outer end of the longitudinal slot 12 so that whenthe cage comes back to this level the curved channel members v9 willmove the guide wheels 17 to the position as indicated in Fig. 1...'lhrought-he linklfthe` lev-er 14 will be-ulorumed to.- moveth'e'linlt. 1.6 outwardly. By the link 16 moving outwardly the platform19 is hinged downwardly. As soon as the cage .moves eith'erup' or'down'from the level the platform 19 vwill he" hinged back to rest against theanges-.

in an upright angular position. The guardsrods @Sane carriedV by theplat form 19.' The inner ends of the guard rods are' riveted to the'platform. 19fw-hile the free ends` extend in' ai vertical. position.Wlien the platform is :in its normah position.'Y

These gnardfrodsf will:- act in place ofy the llVhile tihef platform 1this inv this lposition it will serve as; a st'op or guard' to tleen-vtrance Vofi thef shaft and when: the1 platform; 19 is-` in ai horizontalposition itf willi act as an.-ent1"an'cef-platfoimrtovthe cage, It' thefrom either ofi'tihefra'ils 24. or 25 will'.
